Moving old ERP system running SCO Unix to new hardware or ?????

I am doing some consulting for a company that is running its manufacturing/accounting software (MFG/Pro 7.4h on Progress) on over ten year old HP Netserver LH Pros running SCO Unix 5.0.4.  The company stopped paying the maintenance contracts 7 years ago.  Currently, if they have a hardware failure there is no contingency plan to be able to recover to another server.

I know very little about Unix.  The person working on the servers keeps the systems (development and live servers) healthy, runs backups and makes requested changes.  I am looking for suggestions as to how get this company in a less precarious situation.  

Is it possible to virtualize these servers onto new hardware?  Is there any new hardware that could run the existing OS and software?  What would you advise this company to do?  I am open to all suggestions but please keep in mind that this company does not have deep pockets.

Theoretically, you should be able to run SCO Unix in VMware -- although I haven't tried this

Progress is available for different Unixes. You may want to have a look into Sun Solaris 10 for PCs (can be downloaded free from

Although it's free to download and register production licenses, you can also bay maintenance from Sun.

Sun added binary compatibility for SCO (and Xenix) apps quite some years ago and published several tools for verification of application, too.

Thanks for the comment.  I am waiting for a reply from Sun to see if they think your suggestion is viable.  Also, I did some research on running SCO on VMware.  It is officially not supported though some have been able to get it to work.  It would be ideal to find someone I could hire to creat the virtual SCO 5.0.4 server in VMware.
VMware supports migration from physical to virtual. All you need is free migrator utility, host capable of running free vmware server software (Windows or Linux with extra gig of RAM) and OpenBSD boot floppy to get disk image to vmware's migrator.
Complexity of task depends on if you have RAID controller in your LH3 server.
You need some hour switching system off to acquire disk image and couple more (can be done overnight) probably with consultant to install new disk and net drivers into virtual machine.

If you will get paid for this let me suggest you get one disk image and play around with drivers inside vmware to create perfect migration guide (written step by step is fine) and test it on same disk image.
Then if you are enough prepared migrate system to real vmware using known path.

People here are able to help you with SCO 5.0.5 drivers for vmware, as is vmware support when you purchase one of their paid support packages.

Ir all depends on your time and mony resources. I suggested cheapest way IMO.

Gheist- first, let me apologize for the very late response to your post.  

I am most interested in a solution using vmware.  It turns out my boss would rather I just buy several 7 year old server from Ebay and load them with SCO 5.0.4, the data base and the ERP application and be ready to restore data from tape when the current server goes down.  I will respect his wishes but at the same time I would like to try and work on the virtualization approach.

I won't know until next week if I will be hired on full time or continue as a consultant.  If I get hired on full time I will have the time to work on the virtualization because I won't have to itemize my time.  I will certainly need a lot of help.  I will post again as soon as I find out more.

JustUNIX- thanks for the well wishes.  I was the IT Manager for this company for 4 years prior to leaving a year ago so I have a good relationship here.

By the way, I had a couple of interesting conversations with people from Sun.  They were interested in helping but estimated that there solution would be beyond the budget (lack of budget) I'm dealing with.
